The document presents a new model (ρ, m, and v) that links the wave function with mass and density, offering insights into the behavior of matter and energy systems. It establishes equations that explore relationships between density, volume, mass, and wave functions, culminating in a new equation of light and implications for matter's existence at a critical moment (tf). This work aims to provide a foundational understanding of matter's dynamics in relation to the wave function across infinite spaces.
